short press ENTER to enter the interface for custom tolerance (1% to 50%,
resolution ratio of 1%). Refer to the custom settings of frequency for the
setting method.
5.2.9 Selection of nominal
The method of setting the nominal is as follows:
1. Turn on the instrument and the measurement display is shown, the element with
required nominal should be placed on the test clip of the instrument.
2. Press TOL% to turn on the comparator, and the nominal value is the value of the
measured element with one digit after the decimal point, but it cannot be less than the
minimum unit (for example, if the measured element is 1.0694kΩ , then the nominal is 1kΩ;
for example, if the measured element is 330.92Ω, then the nominal is 330Ω).
3. If the nominal value is not the required one, use the left and right arrow keys to
move the cursor to the nominal, press ENTER to enter the interface for changing the
nominal value.
5.2.10. Selection of equivalent
Due to the non-ideal and distributed parameters of elements, the actual elements
tend to be equivalent with the combination of ideal elements. LCR tester generally uses
two simple equivalent models—series and parallel. Selecting the proper equivalent model
will lead to better measurement results. In general, low-impedance elements (such as that
below 100Ω) should use the series equivalent model; a high impedance element (such as
that above 10kΩ) should use the parallel equivalent model; the equivalent model affects
less the measurement result of the one in between the two above models. Press
AUTO/SER/PAL to switch to the next equivalent (SER, PAL).
5.3. DCR mode
ET1080 Series has the DCR mode except for ET1080B/ET1080A. Long press FREQ
to enter the DCR mode, as shown in figure 9.
